First of all, you might try posting about future issues here:
Digital Duplicators
There are a lot of smart people there that can help you out, many of them even smarter than me.
Still, here's something you can try if time permits-
Turn the machine off, then hold down the "Reset" key while turning the machine on, and keep holding the key down until the display comes to ready. Only do that once, though.
